Determining the Causes of Reproductive Disorders in Nutrias

Betacarotene's effect on hair loss is discussed, with concerns about excessive vitamin A. The user also questions if 15mg melatonin impacts vitamin A levels.

The user is experiencing hair thinning and has a vitamin D deficiency, which they suspect might be causing the issue, but they are also considering androgenic alopecia (AGA) as a cause. They are currently using minoxidil and are unable to get finasteride prescribed, while others suggest addressing the vitamin D deficiency and consulting a dermatologist.

Vitamin D deficiency can hinder hair recovery, and addressing it may help with hair loss. Hair loss may result from various issues like excess DHT, vitamin deficiency, or scalp inflammation.

The conversation discusses hair shedding potentially linked to vitamin D supplementation after Accutane use, with the user suspecting telogen effluvium. Others suggest the hair loss might not be related to vitamin D, considering it a coincidence.

Topical retinol does not affect hair loss and may help hair regrowth. It is different from isotretinoin, which can cause hair loss due to its systemic effects.

Topical Vitamin D3 may stimulate hair growth and has been used for Alopecia Areata. There is a question about the lack of research on its use for Androgenetic Alopecia (AGA).
